Blue stragglers trace the main sequence past the turn-off point toward the blue and luminous region in the color-magnitude diagram of globular clusters. Thus, they appear to be part of a younger population with initial masses higher than the turn-off mass of the globular cluster. However, practically no evidence exists for significant age spreads among stars in globular clusters. The nature and formation mechanisms of the blue straggler population in open and globular clusters is still not fully understood. Commonly proposed theories attempting to explain their high surface temperatures include mass transfer between binary components, the coalescence or merger of two stars in a high-density stellar environment, or a dredge-up of hot material from lower layers in a star's atmosphere due to the gravitation interaction between binary components. In this presentation, we show results of our simultaneous analysis of photometric (Las Campanas 1m) and spectroscopic (CTIO 4m, Magellan 6.5m) time-series data for a eclipsing binary blue straggler system in the southern globular cluster NGC 3201. In addition to photometric light curve and radial velocity curve, we give our estimates of the fundamental stellar parameters of the system.
